update.sh using sh instead of bash causing error

[solariz]

Hey,

just want to point out that the tools/update.sh script is using the interpreter /bin/sh which was done for compatibility reasons I guess.

But on recent distros like deb 12 this throws a compatibility error because the double bracket compare is a enhanced bash feature not available in the compatible SH mode.

-e Make sure to create a backup of the application before you continue.
-e Application root: /var/www/html
./tools/update.sh: 102: [[: not found
-e Current branch: dist
-e You already have the latest version of the application, no upgrade needed.

Fix is simple to move the interpreter to #!/bin/bash and it runs smooth:
